Abstract: A radio-powered apparatus (100) is protected from overloading in strong electromagnetic fields. The apparatus uses a resonant circuitry (120) to receive antenna signals at resonance frequency of the resonant circuitry and to obtain power from the received antenna signals. For restricting energy intake of the resonant circuitry, the resonant circuitry is detuned to operate with a smaller efficiency using an adaptive element in the resonant circuitry.
